Description of key information
Adsorption / desorption:
The Adsorption Coefficient of test substance 2,2,2-trichloroethane-1,1-diol (CAS No.302-17-0)was determined as per the HPLC method (OECD Guideline-121). The Log Koc value was found to be 1.645 ± 0.003 (Koc=45.81) at 25°C.
Additional information
Adsorption / desorption:
The adsorption coefficient Koc in soil and in sewage sludge2,2,2-trichloroethane-1,1-diol (CAS No. 302-17-0)was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 for testing of Chemicals. The reference substances were chosen according to structural similarity with the test substance and calibration graph was prepared. The reference substances were 2- Nitrobenzamide, p – Toluamide, 4 – methyl aniline, Aniline, N – methyl aniline, 2,5 Dichloroaniline having Kocvalue ranging from 1.45 to 2.58. TheLog Kocvalue was found to be1.645 ± 0.003at 25°C.
This value indicates that the substance has low sorption to soil and sediment, moderate migration to ground water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
